HMS Scorpion was a Royal Navy Cruizer-class brig-sloop built by John King at Dover and launched in 1803. She was the first of the class to be built since the launching of Cruizer in 1797. Scorpion had a long and active career during the Napoleonic Wars, earning her crews three clasps to the Naval General Service Medal when the Admiralty authorized it in 1847, two for single-ship actions. She also took a number of prizes. Scorpion was sold in 1819.
